Recent jdt.core builds show many new warnings from API tools with no related change in jdt.core:

• last good build on master: https://ci.eclipse.org/jdt/job/eclipse.jdt.core-Github/job/master/875
• first build with new warnings: https://ci.eclipse.org/jdt/job/eclipse.jdt.core-Github/job/master/878/

Most of these warnings/filters may have been wrong all those years, but at least the following warnings should still be reported, i.e., filters should still be needed:

• https://ci.eclipse.org/jdt/job/eclipse.jdt.core-Github/job/PR-4594/1/apitools/new/source.e013c541-2920-4762-8faf-9cfe063ec3d8/#28
• https://ci.eclipse.org/jdt/job/eclipse.jdt.core-Github/job/PR-4594/1/apitools/new/source.21c0880c-8010-4cb3-939d-7553561f38c0/#28

This makes me wonder if any of these changes are intended?
